For tracing cigarette packets produced by GDH1000 packer, a set of shift code printing device for cigarette packets was designed via analyzing the process of packet blank folding on wheel No. 3. The device was mainly composed of shift code roller, counter roller, outer rotation folder. By the power source of outer rotation folder, the printing device and the mandrel of folding wheel moved synchronously. The gear system and gear box were redesigned to facilitate the printing device retrofitting. The results showed that the device printed clear shift code and featured quick code changing. The time needed for shift code changing reduced from 7.1 to 0.8 min. The additional shift information satisfies the requirements of enterprise standards, and the management and control level of cigarette packing quality is promoted effectively. © 2016, Editorial Office of Tobacco Science & Technology.

To reduce the fluctuation of moisture content in cut stems out of the pneumatic dryer, the control system in the pneumatic dryer was optimized as following: 1) Relocating the testing point of moisture meter from the outlet to the electronic weigher next to pneumatic cut stem conveying. 2) Adding a metering tube to the feeding airlock at the outlet of pneumatic conveying. 3) Optimizing PID control program, resetting the delay time of control points and the data feedback from each processing step and increasing the step of tobacco flow from 2 to 5 kg/s to ensure accurate tobacco flow control. The results showed that after improvement, the moisture content in dried cut stems was 12.61%, which conformed to the technical standard; the qualified rate raised from 78.52% to 99.40%; and the sigma level of process control increased from 2.86 to 4.07. The equipment ran stably, the process control of pneumatic drying and the quality of dried cut stems were promoted. © 2016, Editorial Office of Tobacco Science and Technology. All right reserved.

To optimize the number of automatic guided vehicle (AGV) servicer stations under different cigarette production modes, on the basis of the stochastic service system described by M/G/∞ queuing model, by establishing unit queuing system and taking into account the additivity of Poisson distribution, the formula for calculating the optimal number of servicer stations at different customer source scales was derived. Simulation test and paired comparison indicated that the accuracy of number of AGV servicer stations optimized by M/G/∞ queuing model reached 90%; the model overestimated the actual needs by one service station when customer source scale was small. Adopting the proposed method could estimate the optimal number of servicer stations at different production scales and promote the running efficiency of logistics system for cigarette production effectively. © 2016, Editorial Office of Tobacco Science & Technology.

For preventing emulsion adhesive from developing a solid layer on its surface, an emulsion adhesive stirring and water compensating device was designed and applied to a CT cartoner. Driven by an independent motor, the device stirred the adhesive continuously when the machine was stopped temporarily. The automatic water compensating to adhesive was controlled by a PLC control system. The results of application showed that the solid surface layer was effectively reduced, thereby adhesive waste dropped from 4.22 to 1.08 kg/machine per week. Moreover, the consistence of emulsion adhesive were guaranteed, and maintenance work was decreased.

A packet film detection system for CH of GDX2 packing line was designed with photoelectric detection technology. By installing 5 optical fiber sensors on the turret of CH, when a packet not properly overwrapped was detected, PLC released a signal and that packet would be rejected at the rejecting station. The results of application showed that after installing packet film detection system, the number of cigarette packet with film-related defects reduced from 46 packets to zero per month, the rejection rate of cigarette packet with defective film wrapping reached 99.99%, the false rejecting rate was 0.001%, and the packing quality of cigarette was effectively improved.

To solve the problems of resource waste and space limitation in the process of logistics system optimization, the system was analyzed with the key factor method for simulation optimization by taking the logistics system of waste reclaiming in manufacturing department as an example. A logistics system simulation model was established via a simulation software, data were collected for conducting the goodness of fit test to obtain the running rules of the simulated object, and determine the optimum simulation running cycle or times by the minimum confidence interval of running results. Via key factors screening with ANOVA and Pareto principle, and experimental indexes layering by combining with isolines, the optimal plan with the least resource input was determined. The results showed that according to the isolines drawn on the basis of key factors, number of AGV (Automatic Guided Vehicle) and the way of vehicle marshaling, the optimal index layer fell in the region of handling cycle less than 27.523 min, and the optimal plan was the plan with least resource input (6 AGVs, 1 case tipper, marshaling method No. 3) in that region. The established simulation model agrees with the facts, and gives accurate index data, the system is upgraded obviously and meets the requirements of lean logistics. ©, 2015, Editorial Office of Tobacco Science and Technology.

This paper established a monthly cigarette supply forecasting model to achieve good balance between manufacturing and sales so as to make market-oriented plans. Time series method was used to determine commercial sales forecast model. An innovative algorithm based on seasonal variation forecast method, and two quantitative regulatory forecasting measures were designed. Monthly cigarette supply amount was determined by inventory-to-sales ratio management. Compared with other models the model proved to have good accuracy and consistency. It could synchronized production and sale well and optimize goods distribution and delivery. ©, 2015, State Tobacco Monopoly Bureau and China Tobacco Society. All right reserved.
